Ex Libris 在全球的用户组织在决定公司的产品未来发展方面，扮演着重要的角色。Ex Libris 全面支持这些组织，为具体用户要求的产品改进分配开发资源。
The International Group of Ex Libris Users is an independent, user-initiated organization managed by an elected committee of users. Jiri Kende, of the Free University Berlin, is the current Chair of the organization.
A three-day IGeLU meeting is held annually. Intensive discussions and presentations focus on all aspects of support, upcoming releases, and future development plans.
Ex Libris Users of North America (ELUNA) was founded in the fall of 2005, succeeding the former North American users groups. ELUNA members and Ex Libris staff meet annually to discuss development of Ex Libris products and the Comapny's strategic roadmap. A steering committee is elected at each meeting to manage the affairs of the organization.
